Fuaad solved an absolute value inequality and expressed the solution as negative 12 is less than x comma x is less than 7 What is another way to show Fuaad’s solution?

Fuaad’s solution says that x is greater than −12 and less than 7, so x lies strictly between those two numbers. In set-builder notation, that is {x such that −12 < x < 7}, which is choice D. The endpoints are not included, so the matching interval notation would be (−12, 7).
